摘要
为确定饲喂十字花科类植物对生鲜牛乳中硫氰酸钠含量的影响,选取20头健康产奶乳牛分4组进行饲喂对照试验。除青饲料外各组都饲喂相同的日粮,使用相同的饲养条件,按所喂不同青饲料分别分为A组不饲喂青饲料、B组每顿饲喂2.5 kg卷心菜叶、C组每顿饲喂2.5 kg花椰菜叶以及D组每顿饲喂5 kg花椰菜叶。在排除了组内个体差异和日内差异后,进行了8 d的加量饲喂以及17 d的停止饲喂体内消除试验以便得出饲喂十字花科植物对生鲜牛乳中硫氰酸钠含量影响的规律。实验结果表明,饲喂十字花科类植物可使生鲜牛乳中的硫氰酸钠含量上升,饲喂不同类型的十字花科类植物对硫氰酸钠含量的影响程度有所不同,但是饲喂十字花科类植物不是影响生鲜牛乳中硫氰酸钠含量的唯一因素。
To determine the effect on sodium thiocyanate concentration in raw milk by feeding cruciferous plants, 20 healthy cow were selected and divided into 4 groups. The same feed was used in each group except for the vegetables. Group A was fed with no vegetable. Group B was fed with 2.5 kg cabbage per meal. Group C was fed with 2.5 kg broccoli per meal. Group D was fed with 5 kg broccoli per meal. After the diversity between the cow in same group and the fluctuation during the day were eliminated, the feeding experiment and the elimination test were taken. The results showed that feeding crueiferous plants would improve the sodium thiocyanate concentration in raw milk, and the effect was different due to the different kinds of the plants, but feeding eruciferous plants was not the only factor.
